The main problem is not people who don't unit test their templates but the fact that it's pretty much impossible to cover every possible instantiation of a template, and so it can be pretty easy to miss stuff.
Concepts don't do that either. I do agree we could and should do a better job at testing templates against bare minimum structures that pass their constraints (e.g. test input range algorithms with true input range, which are indeed one-pass). Again, concepts won't help there either - it's not like we claim to support input ranges and then call .save against them. That's not a frequent bug.
